Apple Intelligence is now available on iPhone, iPad, and Mac!
Is it possible to reach USB 3.2 Gen 2×2 (20 Gbps) speed on external USB SSD connected to Mac though USB or Thunderbolt ports? That would mean 2,000 MB/s. For instance, using this SSD:

M1 Macs do not support USB 3.2 Gen 2×2 (20 Gbps). Only half such speed.
It would depend on the Mac you own. The speed of the USB is hardware dependent, so a mere OS upgrade wouldn't necessarily provide the capability if it doesn't exist in the hardware.
The M1 Mini has USB4 (40Gbps) or USB3.1 Gen 2 (10 Gbps).
Thanks. The working link is the one above, but with a slash at the end:

Which Mac madels would be needed to support USB 3.2 Gen 2×2 (20 Gbps) speed on external USB SSD connected to Mac though USB or Thunderbolt ports?
Thunderbolt 4 specifications indicate that USB 3.2 Gen 2×2 (20 Gbps) support is optional. In particular, the iMac 27-inch (Model Identifier iMac18,3; mid 2017) does not support it. Such SSD connected to it only reaches 1,000 MB/s (not 2,000 MB/s). So, my question is which Mac models support USB 3.2 Gen 2×2 (20 Gbps) to reach 20 Gbps (2,000 MB/s) with such SSD.
I'm wondering if it's a hw limit (in M1s) or a driver limit (I never loved Apple's usb drivers if compared to Win and Linuxes). I have an M1 MacMini but just a 10 Gbit usb case with a Samsung 970 nvme inside. A waste, technically speaking, but still very very fast.
I posted here yesterday, yet the message does not show now. So, here it is again.
I wonder if that is possible with the new MacBook Pro models announced yesterday with M1 Pro and M1 Max chips. Someone knows?
According to Kingston:

You'll need a usb-c (or TB 3) at least capable Mac:
Can't view that link but should be an nvme SSD. I've seen 40 gbps external enclosures for sale on the web (I' m interested too having an nvme Samsung 970). Unfortunately prices are above 150us$.
It seems that the problem with the link above is that Safari 15.0 adds
%3E
(at the end of all URL without slash at the end) when clicked. Removing such %3E should fix it. Amazing!
Thanks, but that is for the SSD to work at 10 Gbps (1,000 MB/s). What I want is to know which Mac models support USB 3.2 Gen 2×2 (20 Gbps) to reach 20 Gbps (2,000 MB/s) with such SSD.
If I don' t misunderstand any Mac with Thunderbolt 3, as listed in the second link
As far as I can read on the web only usb4/tb4. Therefore m1 macs.
This is very bad. You therefore need a PC/win or MAYBE next gen M SoCs...
As an aside: M1 Macs will be slower than Intel Mac ports using USB 3.2 gen2 drives. That is why I only use TB3 NVME drives in the proper enclosure.
Ok to every consideration but Barney gave us the answer immediately. I didn't read it carefully... :(
